上下文成本

~503Token（工具定義）
~1.5 KB典型回應大小
極小的注意力影響（128k 上下文的 0.39%）

這是每次將伺服器的工具載入模型上下文時所消耗的約略 token 數量。數量越高，可用於其他工作的注意力就越少。

🟢is_vulnerable(name)

Check if a specific package version has known vulnerabilities. Requires an exact version specifier (e.g., 'requests==2.31.0').

輸入結構描述

{
  "type": "object",
  "properties": {
    "name": {
      "description": "The exact package name and version (e.g., \"requests==2.31.0\", \"numpy==1.24.0\").",
      "type": "string"
    }
  },
  "required": [
    "name"
  ],
  "$schema": "https://json-schema.org/draft/2020-12/schema",
  "title": "IsVulnerableArgs"
}
🟢lookup(cvss_filter, limit, name, retain_passing)

Look up a package by name and (optionally) version number to find which versions are available and/or have vulnerabilities.

輸入結構描述

{
  "type": "object",
  "properties": {
    "cvss_filter": {
      "default": null,
      "description": "CVSS score filter: \"all\" to show all vulnerabilities, \"max\" to show only the\nmaximum observed score, or a number (0.0-10.0) to filter by threshold",
      "nullable": true,
      "type": "string"
    },
    "limit": {
      "description": "When the name is not an exact version, limit the number of recent versions to check.",
      "format": "uint",
      "minimum": 0,
      "nullable": true,
      "type": "integer"
    },
    "name": {
      "description": "The package name to look up (e.g., \"requests\", \"numpy>=2.0\", \"flask==3.0.0\"). Note that when an exact \"==\" version is specified, the `limit` and `retain_passing` parameters have no effect.",
      "type": "string"
    },
    "retain_passing": {
      "description": "'When the name is not an exact version, setting this to True will return refernces for all packages, include those with no vulnerabilities (default: false)",
      "nullable": true,
      "type": "boolean"
    }
  },
  "required": [
    "name"
  ],
  "$schema": "https://json-schema.org/draft/2020-12/schema",
  "title": "LookupArgs"
}
🟢most_recent_not_vulnerable(name)

Find the most recent version of a package that has no known vulnerabilities.

輸入結構描述

{
  "type": "object",
  "properties": {
    "name": {
      "description": "The package name to look up (e.g., \"requests\", \"numpy\", \"flask\").",

    }
  },
  "required": [
    "name"
